Lunvo – Privacy Policy

Last updated: October 19, 2026

Lunvo does not collect, store or share any personal data. Your cycle data never leaves your iPhone.

Your periods, symptoms, moods and notes are stored only on your iPhone, in a file protected by iOS data protection (unreadable while the phone is locked). You can delete everything in Settings at any time.
Lunvo has no server and no account. It contains no analytics, no advertising, no tracking and no third-party code. It makes no network connections of its own.
The data file is part of your normal iPhone backup (iCloud or computer), which you and Apple control. You can leave it out of backups in Lunvo's Settings.
Reminders are local notifications created on your iPhone. By default their wording is discreet and does not mention periods or pills.
Face ID is handled by iOS; Lunvo only receives "unlocked" or "not unlocked".
PDF and CSV reports are created on your iPhone and go only where you choose to send them.
Lunvo does not use Apple Health in this version.
Subscriptions and the one-time Lifetime purchase are handled by Apple; we never see your payment details.

Lunvo's estimates cannot be used for birth control and are not medical advice.
